lic it. known that l, (liaeri'ix W'. Sinnen-is, a citizen of the United States. residing at Bellevue, in the county of Allegheny and State of 5 `ieuiisylvania. liaveinvented certain new and useful improvifn'ients in Casting` llimis: and 1 do hereby declare the following to be a full` clear, and exact description of the invention, such as will enable others skilled in the art to lo which 'it apperttiins to make and use the saine. My invention relates to new and improved means for. casting metals, and more particu# lai-ly to a new and improved casting plant es-A pecially applicable for the manufacture ot' cartrate a car-wheel-casting plant embodyingl my invention` Figure llfisa plan view; Figs. 2, 3, and if, elevationsl views showing' different parts of the plant; Fig'. a top or plan view of a'car; Fig". 6, a side elevational view show- 55 ing' cars, manner of connection between car and drivin@ means, and the location of an equipment-or flask upon a cnr; Fig. 7, a partelevational view and a partsectional view of an equipment or flask, a car, and the means 60 employed im' connecting thc ear with means for drivingtlie saine; and Figs. 'f5 and 9, detail views of screening' apparatus.

vReferring to the drawings, l have shown three cupolas, I, 1",'aiid l", connected to a 65 bull-ladle 2, which latter is arranged to discharge 'molten' metal into a pouring-ladle El, carried by the pouring-crane L Pouring-lan dle 3 isarranged to swing' directly over a portion of an endless track 5, on which cars (i, '10 carrying` equipments or flasks T. travel. 'l`hel terni "equipment is used to designate the cope u, cliillcr b, drag c, and bottom board, which comprise a flask eii'iployed in the manufacture of car-wheels. The form of cars 7 5 or carriers for the equipments or flasks is particularly shown by Figs. 5 and (5 of the drawings, each car being' designed to carry sets of two equipments or flasks thereon, While l 4have shown cars especially applicable. for the 8o class of work for whichtliey are called upon to perform, other ysuitable forms of cars or carriers maybe substituted in place of those ".,sliowin ln. building a@ plant' for carwheel iiiniiufactuie it is necessary to bear in mind the great weight oftheequipments, and a cai'- rier capable of carrying,` one or more car-wheel equipments as well asthe other parts anil ap- `overcomethenianydisadvauta-gesencountered paratus must be designed accordingly.` All 40 intlisystcinsheretoforei'nvoguein-tlieinanuthe cars are coupled together and forma train 9o facture of car-wl'ieeis, to lessen the original which is run by soinesuitable power. 'lhis c'ost of a plant designed for this purpose, to train may be run continuously or interinitn reduce the cost of manufacture, toiniprove tently, as desired. The means for drivingthe the quality of the wlieels, and to provide new car as illustrated comprise an electric motor To this end my invention consists of a casting plant, allras hereinafter described and Clai in ed.

While llhavc shown my invention embodied 2.0 in a casting` plant for thc'nianufacture of carwlieels and' shall describe suoli a. plant in this specification, a plant constructed with certain inediiications in the apparat us 'or some changes in the arrangement of the4 same could be ad- 25 vantageous'ly employed for the manufacture of other castings and would come within the sciiipe of the present invention.

ln the manufacture of cast car-wheels heretofore practcedthe work has been divided 3o up ainoiue,` a number of melders, each having a space in the plant allotted to him, and most,l if not all, thewoik done by lianddabor in a slow, expensive, and 'frequently in an unsatisfactory manner, the quality of the work pending upon the skill, judgment, and disposition of the operators.

Among' the objects of my invention are to .T andiiiiprevedineansfor iierioriiiingl thcwork 8, which actuates a systemof gearing', and 95 before done byniaimal labor, whereby the shafts 9, each ofthe lattenbeing provided with `making of the wheels vis greatly expedited a driving-pinion 10, which is adapted toenand the work performed in.a.coiitiiiii ous and gage with a rack or pinion bar 11, securely orderiy manner. attached to each car. '1t is obvious that the in the accompanying;drawings, which 1llusnumber ot shafts 9 and their pinions 10, it it1oo' s found necessary, may he more than two and '.hnt instead of empioying en electric motor some other form ot' motor, such as e steznnengine., may he employed.

For he purpose of pleeing :zn equipment or iiesii. upon sind removing it from n cer l provide n traveling; crane, iridieated by the nnrnernl i2.

After the ecuipnients are placed on the cars end the trein started the operation of preparen equipment for the reception of the smid,y ac., is commenced hy placingr n pattern in "the drag part of the equipment et some snitehie point eiong the track, es :it 13. in describing` the phint and the different operetione have deemed it adviselile to foilow one equipment or flesh from the time the pattern is pinned therein nntii that equipment hes completed its trip eronnd the track. The di rection of travel of the cars is shown hy the arrows. Vy'hen the pattern is in position within the drag part c, e. sniicient quantity of tracing-send is first supplied, after which the drag' is fiiied with molding-sand, The sand is then rammed and the equipment relied over end substantially the seme operations repented with respect to the cope part nl.. For carrying' out these steps in the manufectnreof the wheels i provide send-bins, hoisting npparatus, and machines for rnmming the Send. The send-bins l and 14 are supported over the track and cnrs'. From these bins sand is fed to the drag and cope in themenner perticuleriy shown hy Fig. 3 through spouts 15, the amonnt of send delivered beingl regulated by suitable means operated by levers i5. rihe purpose ofthe two send-delivery sponts :it the left end center of the loins i4" is to fur? nish additional send if it is found desirable to do rihis additional send is rammed by an operator. in the figure just mentioned the hins le conta-in the fecingesnnd and the bins il?" the mold in ,fg-send. usually consists of pulverized or iine coal mixed with the ordinary molding-send, is formed hy adding the proper quantity of the coal to the send et some suitable point before the send reaches the bins 14. After the send is placed in the dra-g the operation of peening the tienge is performed by n suitable ram ming-mechine li', after which smother machine 18 is employed for completing the reniining. The sand is then smoothed off by n plate i9, thereby iinishing the drag', with the ex# eeption of venting', which is done by an operator. By the time the wortY on the dran; is iinished the cnr carrying the same wiliihme arrived under n hoisting device provided with n buil 21, adapted to engage pins or ings on the chiller part of the equipment. The equipment oi' lizislcs hein;y raised from the cnr by hoist 20. bottom born-d 22, which when not in use is eerrird on n enr, ns shown. is :niet-hed. in position the equipment while suspended The facing-send, which 20, which is A'l'i'ivrthebottom hom-d is i Weens I nhove. the cnr' is turned over, so as to bring the i eopepnrt withitsdish uppermost. 'Vhen this is ncconnjilishod, the equipment is lowered :md i' placed is position on the eer. Facing-'sand und molding-send are now fed to the cope and l the peening of the rim, bers, and dish perl llm'medhy 'ramming-machine 23, after which i more sand is furnished to the cope and the operation of putting the hars of the cope sind vfinishing,V the dish is performed by means o the lnitt-nmehine 24. The cope is then vented end the heed-bloclrdrawn. The rfnnming-niechinos 1.?. 18, Q3, and 2e are carried on "en overhead supporti i and are adapted to travel thereon. it may sometimes be desirable oi preferable to rem the sand by hand, lAnd when' this done of course the rennming-machines just described are not employed.

A crane arranged to'trnrel on e support ,26, is provided with e hoisting device 2'?, haw ing e bail 28, which latter when lowered over e cer engages with ings on the Chiller. The object of these means is to raise the cope in order that the pattern maybe withdrawn and the cores and cheplets set in position. Din ing the operation of withdrnwingthe pattern, Sac., crime 25 is moved along with the cer om rying the fiesli from which the pattern is he? ing' removed. This movement of the crane is 1 effected by the employment of a si yinging erin :29, ez/:tending downwardly from the crane end engregingwith the car. Arm 29 is swunginto and out of engagement with the ein' by the operator who withdraws Vthe pattern. The vsupport may, ii LAireferred, be inclined in `such n manner as to cause the crane to return by gravity to a position ready to hoist the foilowingl cope and chille-r. The pattern having been withdrawn, the cope and chiller ere iowered to the drag, and after being locked therem to the equipment or flask is reedytoreeeive the molten metal. A chin-ge of metal is supt4 plied from the pouring-ladle 3, .which Swings over the. cars, as described, and particuiarly illustrated by Fig. 1. The distance between. the pouring-ladle and an overhead crane 30 is sufficient to to assume a condition ready for what is termed the "shaking-out stops in the method of manufacture. These steps comprise, tirstthe removal of the equipment, with the exception of the bottom board, from the enr and pideu i ing it cope down on the vacant space ahead; second, transferring 'the cast wheel from the cin' upon which it was formed to some` suitn able :md convenient place within reachof a pitting-erzme, (not shown,) and, finally, c anging; the bottom board to e vertical position. For the purpose of carrying ont these steps I employ the crnne 30, which travels on a support 31 and carries means for removing the j erniipment and the cast Wheel, as shown hy t. rEhe means hewn comprise a hoist ing device 32, having a heil 33, and e hoist i 31?, provided with tongs 35. After the iiasl:
